Hey guys,

Just wondering if any of you would be able to answer I question I have about my R32 GTS-T

when I bought the car it came with a generic aftermarket pod filter, it was pretty old and crap looking (plus a defect)

I finally managed to get a standard R32 air box and replaced the pod filter with the standard box (plus a new air filter).

However, when I drive now the sound of my Blow Off Valve is almost inaudible.

When I had my old pod filter, the sound was extremely loud, and from 2,200 revs up I could hear the build up, and on release at 3 - 4,000 revs it would make a loud hiss / vacuum sound. With the standard air box in its almost 1/4th the volume of what it used to sound like.

It actually runs better and smoother on the standard air box, but I just don't understand why changing a pod filter to the standard air box would make such a drastic difference.

Would anyone be able to explain this to me? I double checked all of the hoses and clamps, and there is no leak anywhere, and the turbo still acts exactly as it used to (in terms of build up and pressure), just the sound has changed.

Would really like to know if this is normal or if I could have damaged something.

Regards

absolutely normal. airbox is doing it correctly and quietening down bov noises. most people do this to avoid unwanted attention.

suggest getting a good panel filter to keep same or better flow (then pod) of air to turbo... stock panel filters are a little restrictive.

Thanks for the quick reply guys!

That makes me feel much better as it sounds like I didn't break anything in the process of putting in the standard Air Box.

The old pod filter that I removed was a 'Tenzo Filter', and it also had a large black shield that would cover the sides. Is the old filter something I should keep a hold of? I removed the Boss kit (the adapter from the Air Flow Meter to the base of the filter), the Pod filter itself, and the metal shield that went around it.

These things worth anything? should I throw it on Ebay or try and sell it here?

The air filter I put inside the standard box was just a regular one I got from Supercheap Auto (that suits the R32).

are there any good brands that will make a difference? Also if it is an enclosed box, would any other filter really make a noticeable difference?

Thanks again guys for the quick reply!

I also use a k&n filter in my airbox. Just don't use an oiled filter as it will mess up your air flow meter constantly.

    • I have engineer in my job title One of or motto's though is "we make and we break"
    • This is actually 2 whole different trains of thought that need to be addressed separately. No, as Matt says above, "Engineer" is not a directly protected title. A lot of guys who just do mechanical design via CAD, with or without even some sort of associate diploma in engineering, often have the job title of "Design Engineer". A train driver can probably still describe themselves as an engineer. But, to usefully get employment with anyone as a proper engineer, you're going to have to have at least the necessary and relevant degree qualification. You're not going to get a job as an electrical engineer if you have a chem eng degree, unless you can demonstrate x number of years of working in that capacity, sufficient knowledge, etc. Having the degree is at least in indication that you've seen the relevant text books, even if you haven't read them (like pretty much the last 10 years of graduates!). To be a self employed engineer.....you could get away with quite a lot pretending that you're suitably qualified, without actually being a proper engineer. But, you will find yourself unable to work for a large section of the client space because a lot demand CVs and capability statements when considering contracting for any engineering work these days. Insurances too. If you're not a proper engineer, it will be much harder to obtain proper PI insurance. Insurance companies have gotten hip to that. The "Professional Engineer" thing is a thing in Australia. If you have the right qualifications and experience you can apply to the relevant engineering top level body (mostly Engineers Australia, the less said about whom, the better), to be assessed and approved as a Chartered Professional Engineer, CPE. There are high bars to get over and a requirement for CPD to maintain it. The RPEQ thing is similar-ish, in that you have to demonstrate and maintain, but the bars are a little lower. It is required to be RPEQ in order to sign off as an engineer on any engineering design in Queensland. The other states haven't fully followed suit yet. There's "engineering" and there's "engineering". Being an engineer that signs off on timber (or even steel) frames for housing projects, council creek crossing bridges, etc, is a flavour of civil engineering that barely warrants the name, description and degree. That would be soul crushing work anyway. Being an automotive engineer working in the space where you have to sign off on modifications to cars and trucks would also be similarly soul crushing. At least partly because of the level of clientelle, their expecations, depths of bank balance, etc. And that brings us to your second question. No, we do not have professional engineers "do vehicle inspections". Well, not the regular roadworthies, etc etc. That's done by mechanics. There might be some vehicle standards engineers at the various state govco inspection stations where cars go to get defects cleared and so on, but that's because they (the cars) are there specifically for defect inspection and clearance and so the stakes are a little higher than on an annual lights and brakes working check. But, if you modify a vehicle in Australia, you have to get it engineered. A suitably qualified (and effectively licensed, which I will get back to) automotive engineer will have to go over the application, advise on what would be required to make the mods legal, supervise some parts of the work, inspect and test the results, and sign off. The "licensed" aspect comes from there being a list of approved engineers to do these things in each state. They have to jump through hoops set up by the govco vehicle standards divisions that mean only the suitably qualified can offer to and approve such mods.
    • It's got a problem Prank... It looks like both washer spray caps have fallen off this car... 😛
    • Meh, it's only got to last another 10 years or so until you'll be forbidden to drive it. Keep it dry and forget about it.
    • The title of Engineer is not protected. However different states have different rules about what an Engineer requires to operate. Engineering for a motor vehicle modification is very different to engineering for a bridge, electronics, etc, including what that engineer needs as certifications.   In Canberra, "Engineer" is the loosest category with basically nothing stopping you calling yourself and engineer and designing a bridge or building. From what I've reviewed, QLD has the strictest requirements through RPEIQ.
